EAS 762:2013 Foreword Development of the East African Standards has been necessitated by the need for harmonizing requirements governing quality of products and services in the East African Community. It is envisaged that through harmonized standardization, trade barriers that are encountered when goods and services are exchanged within the Community will be removed. In order to achieve this objective, the Community established an East African Standards Committee mandated to develop and issue East African Standards. The Committee is composed of representatives of the National Standards Bodies in Partner States, together with the representatives from the private sectors and consumer organizations. Draft East African Standards are circulated to stakeholders through the National Standards Bodies in the Partner States. The comments received are discussed and incorporated before finalization of standards, in accordance with the procedures of the Community. East African Standards are subject to review, to keep pace with technological advances. Users of the East African Standards are therefore expected to ensure that they always have the latest versions of the standards they are implementing. EAS 762:2013 was prepared by Technical Committee EAS/TC 014, Cereals, Pulses and related products iv EAC 2013 All rights reserved
EAS 762:2013 Introduction This standard has been developed to take into account: a) the needs of the market for the product; b) the need to facilitate fair domestic, regional and international trade and prevent technical barriers to trade by establishing a common trading language for buyers and sellers; c) the structure of the CODEX, UNECE, USA, ISO and other internationally significant standards; d) the needs of the producers in gaining knowledge of market standards, conformity assessment, commercial cultivars and crop production process; e) the need to transport the product in a manner that ensures keeping of quality until it reaches the consumer; f) the need for the plant protection authority to certify, through a simplified form, that the product is fit for cross-border and international trade without carrying plant disease vectors; g) the need to promote good agricultural practices that will enhance wider market access, involvement of small-scale traders and hence making farming a viable means of wealth creation; and h) the need to ensure a reliable production base of consistent and safe crops that meet customer requirements.

EAST AFRICAN STANDARD EAS 762:2013 Dry soybeans Specification 1 Scope This East African Standard specifies the requirements and methods of sampling and test for dry whole soybeans of varieties (cultivars) grown from Glycine max (L.) Merr. intended for human consumption. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EAS 38, Labelling of prepackaged foods Specification EAS 39, Hygiene in the food and drink manufacturing industry Code of practice EAS 79, Cereals and pulses as grain Methods of sampling EAS 217, Methods for the microbiological examination of foods ISO 605, Pulses Determination of impurities, size, foreign odours, insects, and species and variety Test methods ISO 711, Cereals and cereal products Determination of moisture content (Basic reference method) ISO 712, Cereals and cereal products Determination of moisture content Routine reference method ISO 13690, Cereals, pulses and milled products Sampling of static batches ISO 16050, Foodstuffs Determination of aflatoxin B 1, and the total content of aflatoxin B 1, B 2, G 1 and G 2 in cereals, nuts and derived products High performance liquid chromatographic method CODEX Stan 193, Codex general Standards for contaminants and toxins in food and feed 3 Terms and definitions For the purpose of this standard, the following terms and definitions shall apply. 3.1 soybeans whole mature dry seeds of varieties (Glycine max (L.) Merr.) 3.2 damaged/defective soybeans and pieces of soybeans that are badly ground-damaged, badly weather-damaged, diseased, frostdamaged, germ-damaged, heat-damaged, insect-bored, mould-damaged, sprout-damaged, stinkbug-stung, or EAC 2013 All rights reserved 1
otherwise materially damaged. Stinkbug-stung kernels are considered damaged kernels at the rate of onefourth of the actual percentage of the stung kernels. 3.3 foreign matter any extraneous matter than dry soybeans or other food grains comprising of a) "inorganic matter" includes metallic pieces, shale, glass, dust, sand, gravel, stones, dirt, pebbles, lumps or earth, clay, mud and animal filth etc; b) "organic matter" consisting of detached seed coats, straws, weeds and other inedible grains etc. 3.4 immature characterized by a green exterior appearance in conjunction with green discolouration penetrating the cotyledon. Examination of the cotyledons is determined by cutting the soybeans in cross section. For grading purposes, immature damaged soybeans are considered as part of the Total Damage grade specification. Soybeans that are green in appearance and have no discolouration of the cotyledon or just a halo of green around the outside of the cotyledon are to be assessed against the overall colour of the sample. 3.5 poisonous, toxic and/or harmful seed which if present in quantities above permissible limit may have damaging or dangerous effect on health, organoleptic properties or technological performance such as Jimson weed datura (D. fastuosa Linn and D. stramonium Linn.) corn cokle (Agrostemma githago L., Machai Lallium remulenum Linn.) Akra (Vicia species), Argemone mexicana, Khesari and other seeds that are commonly recognized as harmful to health 3.6 rancidity characterized by a deep pink discolouration on the seed coat and varying degrees of discolouration of the cotyledon 3.7 splits broken soybean seeds that are less than three-quarters of the whole seed, and cotyledons that are loosely held together by the seed coat 3.8 food grade material packaging material, made of substances which are safe and suitable for their intended use and which will not impart any toxic substance or undesirable odour or flavour to the product 4 Quality requirements 4.1 General requirements Soybeans shall be: a) grain that consists of 50 % or more of whole or broken soybeans (Glycine max (L.) Merr.) that will not pass through an 8/64 round-hole sieve and not more than 10.0 % of other grains for which standards have been established; b) hard, clean, wholesome, uniform in size, shape, colour and in sound merchantable condition; NOTE The colour of soybeans may be yellow, green, brown or black. c) safe and suitable for human consumption; 2 EAC 2013 All rights reserved
